My Buying Guides on Xs Gs Marlin 1895/45-70 W/Bo Sight Dimensions

When I first started looking into the Xs Gs Marlin 1895 chambered in 45-70 with the BO (Battle Optics) sight, I quickly realized that understanding the exact dimensions and fitment was crucial. Whether you’re upgrading your rifle’s sight or just want to know what you’re working with, here’s what I learned along the way.

Understanding the Marlin 1895/45-70 Platform

Before diving into the sight dimensions, it’s important to know the base rifle. The Marlin 1895 is a lever-action rifle known for its robust design and classic styling. The 45-70 cartridge it chambers is a big-bore round, requiring a sturdy build and sight that can handle recoil and provide clear target acquisition.

Why the XS Battle Optics Sight?

I chose the XS Battle Optics (BO) sight because it offers a rugged, reliable aiming system designed for quick target acquisition. The BO sight is popular among hunters and tactical shooters alike. However, fitting it properly on a Marlin 1895 requires attention to dimensions to ensure compatibility and maintain the rifle’s balance.

Key Dimensions to Consider

Here are the critical measurements I focused on when evaluating the XS GS Marlin 1895 with the BO sight:

  • Base Mount Dimensions: The Marlin 1895 usually comes with a specific scope base or receiver rail. I checked the length and width to confirm the BO sight mount would sit securely without overhang or interference. Typically, the base is around 7 to 8 inches long, but exact measurements can vary by model year.
  • Height of the Sight: The BO sight adds height above the receiver. I measured the height from the bore axis to the top of the sight’s optic window. This is essential to ensure a proper cheek weld and sight alignment when shooting.
  • Length and Weight of the Sight: Knowing the sight’s length helps me anticipate how much it extends over the barrel, affecting handling. Weight distribution is also key, as a heavier sight up front can change the rifle’s balance.
  • Mounting Hole Spacing: The screw holes on the base where the sight attaches must line up precisely. I verified the hole pattern on my Marlin 1895’s receiver to match the XS BO sight’s mount.

My Measurement Tips

To get accurate dimensions, I used digital calipers for smaller parts and a tape measure for overall length. I recommend taking these measurements yourself or consulting the manufacturer’s specs before purchasing. Sometimes, aftermarket mounts or slight model variations can affect compatibility.

Additional Considerations

  • Eye Relief: The BO sight’s eye relief distance plays a role in comfort and shooting accuracy. I made sure it matched my preferred shooting stance.
  • Durability and Recoil Resistance: The 45-70 round generates significant recoil, so I looked for a sight and mounting system rated for heavy recoil use.
  • Installation Ease: Some sights require gunsmithing or custom mounts. I preferred a setup with straightforward installation and minimal permanent modifications.

Final Thoughts

By paying close attention to the exact dimensions and fitment of the XS GS Battle Optics sight on my Marlin 1895/45-70, I ensured a secure, comfortable, and effective shooting setup. If you’re considering this combination, take your time measuring and matching specs—your shooting experience will be much better for it.
